ABSTRACT

Described are cyclohexenyl-alpha-alkyl acrolein derivatives defined according to the generic structure: ##STR1## wherein R 1 , R 2 , R 3  and R 4  represent hydrogen or methyl with the proviso that one, two or three of R 1 , R 2 , R 3  and R 4  represent methyl; wherein R 5  represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the &#34;cis&#34; or &#34;trans&#34; juxtaposition of the moieties hydrogen, R 5 , cyclohexenyl and carboxaldehyde about the carbon-carbon double bond useful for augmenting or enhancing the aroma or taste of foodstuffs or chewing gums.

This application is a divisional of application for U.S. Letters Patent, Ser. No. 398,953 filed on July 16, 1982.

BACKGROUND OF THE INVENTION

The instant invention provides the cyclohexenyl-alpha-alkyl acrolein derivatives defined according to the generic structure: ##STR2## wherein R₁, R₂, R₃ and R₄ represent hydrogen or methyl with the proviso that one, two or three of R₁, R₂, R₃ and R₄ represent methyl; wherein R₅ represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R₅, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond; and uses thereof for their organoleptic properties in consumable materials.

Materials which provide powerful, green, cumin-like, spicy, cinnamon-like, natural orris, floral (violet-like), animalic, musky, floral (lily/lilac), ionone-like, orris-like, burnt orris, pungent fresh green, woody and "tropical rain forest" aromas are highly desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfumery compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

By the same token, materials which can provide powerful, spicy, cinnamon, cumin-like, green and dandelion leaf-like aroma and taste nuances are highly desirable in the art of flavorings for foodstuffs, toothpastes, chewing gums, chewing tobaccos and medicinal products. Many of the natural materials which provide such flavor notes and contribute such desired nuances to flavoring compositions are high in costs, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

Hay-clover-like, sweet, rich-tobacco, floral, fruity, green and earthy aroma and taste nuances are highly desirable for many uses in flavoring smoking tobacco compositions and smoking tobacco article components.

Arctander "Perfume and Flavor Chemicals (Aroma Chemicals)", Volume II, at monograph 2896, discloses that tetrahydro cinnamic aldehyde having the structure: ##STR3## has a powerful, sweet-green, leafy, delicately creamy odor. Arctander further discloses:

"The title aldehyde, commonly referred to under the title name, was developed many years ago in continuation of the search for interesting aldehydes from the Claisen reaction, by which Cinnamic aldehyde had been produced. It was also based upon a new methods of obtaining cyclohexene aldehydes and homologues of same.

The subject material has found some application in perfumery, and so has the Cyclohexene carboxaldehyde from which it is made. The parent cyclic aldehyde has a powerful green-leafy odor, and it was interesting to see what type odor could be obtained by the Claisen condensation.

Although rarely offered under its proper chemical name, this material is still used in various perfume specialties and bases for its refreshing, green note, sometimes useful in Citrus compositions, but also used in Chypres, Fougeres, etc. in combination with Oakmoss, Lavender, etc.

It is produced from Acrolein and Butadiene to make Cyclohex-3-enealdehyde. By condensation (Claisen) with Acetaldehyde the title material is obtained."

Arctander, at monograph 2896, refers to French Pat. No. 672025 published on Dec. 21, 1929. In said French Pat. No. 672025, the Diels-Alder reactions of acrolein derivatives with conjugated dienes to produce cyclohexene carboxaldehydes are disclosed. Thus, for example, the reaction: ##STR4## is disclosed to produce a perfumery compound. Furthermore, French Pat. No. 672025 discloses that the resulting carboxaldehydes can be further reacted with ketones to produce irone-type derivatives at page 3, lines 75-82 and at page 4, lines 1-5.

Neither the French Pat. No. 672025 nor the Arctander reference discloses or infers that the compounds defined according to the structure: ##STR5## has desirable organoleptic properties which are unexpected, unobvious and advantageous.

Arctander "Perfume and Flavor Chemicals (Aroma Chemicals)", Volume I, at monograph 761 discloses the use of iso-Cyclocitral which is a mixture of compounds having the structures: ##STR6## for its organoleptic properties thusly: "Powerful, and diffusive, foilage-green, "dark"-weedy and dry odor, sometimes described as "Flower-shop odor". The earthy and wet-green notes are quite natural in high dilution and resemble the odor of stems from plants and flowers fresh from the soil.

Finds use in perfume compositions where it blends excellently with Oakmoss products (compensates for sweetness and lifts the topnote), with Ionones (freshness), Geranium and Galbanum (enhances the green and "vegetable" notes), etc.

On account of its modest cost it also finds its way into masking odors for industrial purposes. Its power compensates for its cost (usually slightly less than Citral) for such purposes.

Produced by a Diels-Alder type condensation of 2-Methyl-2,4-pentadiene and Crotonaldehyde. The reaction product is a mixture of isomers commercially called iso-Cyclocitral (after rectification)".

At monographs 762 and 763, Arctander describes alpha-Cyclocitrylidene Acetaldehyde and beta-Cyclocitrylidene Acetaldehyde having the structures, respectively: ##STR7## thusly: 762: alpha-Cyclocitrylidene Acetaldehyde . . .

"Mild floral-woody, somewhat oily-herbaceous odor, remotely reminiscent of Rose with similarity to the odor of hydrogenated Ionones.

Suggested for use in perfume compositions. It brings a certain amount of floral lift to Rose compositions, and performs fairly well even in soap. However, the cost of the rarely offered and never readily available lots are rather discouraging to the perfumer, and it is most conceivable that this material can be left out of the perfumer's library without any great loss.

Produced from alpha-Cyclocitral and Acetaldehyde by condensation."

763: beta-Cyclocitrylidene Acetaldehyde . . .

"Sweet-woody, rather heavy odor, resembling that of beta-Ionone. More fruity than really floral, but not as tenacious as the Ionone.

Suggested for use in perfume compositions, but since it does not offer any new or unusual odor characteristics, and it cannot be produced in economical competition to beta-Ionone, there is little or no chance that it will ever become a standard shelf ingredient for the perfumer.

Produced from beta-Cyclocitral and Acetaldehyde by condensation."

U.S. Pat. No. 3,031,507 discloses the use in perfumery of cyclohexylcrotonaldehyde having the structure: ##STR8##

U.S. Pat. No. 3,313,843 discloses the use of cinnamaldehyde derivatives having the structure: ##STR9## wherein R is hydrogen or methyl as intermediates for preparing other compounds.

Nothing in the prior art, above cited, or any other prior art infers or discloses the compounds having the generic structure: ##STR10## wherein R₁, R₂, R₃ and R₄ represent hydrogen or methyl with the proviso that one, two or three of R₁, R₂, R₃ and R₄ represent methyl; wherein R₅ represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R₅, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.

Nothing in the prior art discloses that such compounds having the structure: ##STR11## wherein R₁, R₂, R₃ and R₄ represent hydrogen or methyl with the proviso that one, two or three of R₁, R₂, R₃ and R₄ represent methyl; wherein R₅ represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R₅, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond; has such unexpected, unobvious and advantageous organoleptic properties.

The new method for synthesis of alpha-Atlantone"), according to the reactions: ##STR35## wherein R₁, R₂, R₃ and R₄ represent hydrogen or methyl with the proviso that one, two or three of R₁, R₂, R₃ and R₄ represent methyl; wherein R₅ represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R₅, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.

In the first reaction sequence, the Diels-Alder reaction: ##STR36## is carried out in accordance with the procedure of French Pat. No. 672,025 published on Dec. 21, 1929, the disclosure for which is incorporated by reference herein. In addition, the Diels-Alder reaction can be carried out at lower temperatures using Lewis acid catalyst such as stannic chloride, zinc chloride, aluminum diethyl chloride or ethyl aluminum dichloride (e.g., temperatures of 10°-40° C.). The resultant cyclohexene carboxaldehyde defined according to the structure: ##STR37## is then reacted via an aldol condensation reaction with n-propanol or n-butanal having the structure: ##STR38## according to the reaction: ##STR39## wherein R₁, R₂, R₃ and R₄ represent hydrogen or methyl with the proviso that one, two or three of R₁, R₂, R₃ and R₄ represent methyl; wherein R₅ represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R₅, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.

The aldol condensation is carried out at standard aldol condensation reaction conditions using a base such as sodium hydroxide, potassium hydroxide, calcium hydroxide, lithium hydroxide or barium hydroxide (in, for example, a Soxhlet apparatus) at temperatures in the range of from about 10° C. up to about 80° C. in the presence of an inert compatibles such as methyl alcohol or ethyl alcohol. When using a barium hydroxide catalyst, the barium hydroxide is kept in the Soxhlet thimble and the reactants are refluxed at the reflux temperature of the reaction mass. The reaction can be carried out at atmospheric or super atmospheric pressures. At super atmospheric pressures the time for reaction completion is less than the time for reaction completion when carrying out the reaction at atmospheric pressure in view of the higher temperature of reaction. The mole ratio of aldehyde having the structure: ##STR40## to aldehyde having the structure: ##STR41## is preferably from about 0.5:1 up to about 1:0.5 with a mole ratio of 1:1 being preferred.

At the end of the reaction, the reaction mass is neutralized and the solvent is stripped. The reaction product is then distilled as by fractional distillation in vacuo to yield the desired products defined according to the structure: ##STR42## wherein R₁, R₂, R₃ and R₄ represent hydrogen or methyl with the proviso that one, two or three of R₁, R₂, R₃ and R₄ represent methyl; wherein R₅ represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R₅, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.

The conditions for the Vilsmeier Formulation are the same as those set forth in the Dauphin paper, the disclosure of which is incorporated by reference herein.

The resultant product is a mixture of "cis" and "trans" isomers, to wit: ##STR43## and, in addition, is a mixture of "endo" and "exo" isomers, for example: ##STR44## which represents, respectively, "cis" or "E" exo, exo, exo or endo, endo, endo. The different products can be trapped out using commercial GLC separations, but more practically they can be used in admixture for their collective organoleptic properties as set forth, infra and supra. Both the Vilsmeier Formulation and the foregoing Aldol condensation techniques however, yield products which are primarily "E" isomers, those which are defined according to the structure: in preponderance over the "Z" isomers.

It is noteworthy that the compounds of our invention have several asymmetric carbon atoms which give rise to a vast number of "endo" and "exo" isomers in addition to the "cis" and "trans" isomers. Thusly, the "*" is indicative of the location of the asymmetric carbon atoms in the following structure: ##STR45## wherein R₁, R₂, R₃ and R₄ represent hydrogen or methyl with the proviso that one, two or three of R₁, R₂, R₃ and R₄ represent methyl; wherein R₅ represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R₅, cyclohexenyl carboxaldehyde about the carbon-carbon double bond.

When the cyclohexnyl-alpha-alkyl acrolein derivatives of our invention are used as food flavor adjuvants, the nature of the co-ingredients included with said cyclohexenyl-alpha-alkyl acrolein derivatives of our invention in formulating the product composition will also serve to alter, modify, augment or enhance the organoleptic characteristics of the ultimate foodstuff treated therewith.

As used herein in regard to flavors, the terms "alter", "modify" and "augment" in their various forms means "supplying or imparting flavor character or note to otherwise bland, relatively tasteless substances or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or taste".

The term "enhance" is used herein to mean the intensification of a flavor or aroma characteristic or note without the modification of the quality thereof. Thus, "enhancement" of a flavor or aroma means that the enhancement agent does not add any additional flavor note.

As used herein, the term "foodstuff" includes both solid and liquid ingestible material which usally do, but need not, have nutritional value. Thus, foodstuffs include soups, convenience foods, beverages, dairy products, candies, vegetables, cereals, soft drinks, snacks, and the like.

As used herein, the term "medicinal product" includes both solids and liquids which are ingestible, non-toxic materials which have medicinal value such as cough syrups, cough drops, aspirin and chewable medicinal tablets.

The term "chewing gum" is intended to mean a composition which comprises a substantially water insoluble, chewable plastic gum base such as chicle, or substitutes therefor, including jelutong, guttakay, rubber or certain comestible natural or synthetic resins or waxes. Incorporated with the gum base in admixture therwith may be plasticizers or softening agents, e.g., glycerine, and a flavoring composition which incorporates one or more of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, sweetening agents which may be sugars, including sucrose or dextrose and/or artificial sweeteners such as cyclamates or saccharin. Other optional ingredients may also be present.

Substances suitable for use herein as co-ingredients or flavoring adjuvants are well known in the art for such use, being extensively described in the relevant literature. It is a requirement that any such material be "ingestibly" acceptable and thus non-toxic and otherwise non-deleterious particularly from an organoleptic standpoint whereby the ultimate flavor and/or aroma of the consumable material used is not caused to have unacceptable aroma and taste nuances. Such materials may in general be characterised as flavoring adjuvants or vehicles comprising, broadly, stabilizers, thickeners, surface active agents, conditioners, other flavorants and flavor intensifiers.

The specific flavoring adjuvant selected for use may be either solid or liquid depending upon the desired physical form of the ultimate product, i.e., foodstuff, whether simulated or natural, and should, in any event, (i) be organoleptically compatable with the oxabicyclooctane derivatives and the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention by not covering or spoiling the organoleptic properties (aroma and/or taste) thereof; (ii) be non-reactive with the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention; and (iii) be capable of providing an environment in which the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be dispersed or admixed to provide a homogeneous medium. In addition, selection of one or more flavoring adjuvants, as well as the quantities thereof will depend upon the precise organoleptic character desired in the finished product. Thus, in the case of flavoring compositions, ingredient selection will vary in accordance with the foodstuff, chewing gum, medicinal product or toothpaste to which the flavor and/or aroma are to be imparted, modified, altered or enhanced. In contradistinction, in the preparation of solid products, e.g., simulated foodstuffs, ingredients capable of providing normally solid compositions should be selected wuch as various cellulose derivatives.

As will be appreciated by those skilled in the art, the amount of cyclohexenyl-alpha-alkyl acrolein derivatives of our invention employed in a particular instance can vary over a relatively wide range, depending upon the desired organoleptic effects to be achieved. Thus, correspondingly, greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored (e.g., with a spice flavor or a specific black pepper-like-flavor) is relatively bland to the taste whereas relatively minor quantities may suffice for purposes of enhancing the composition merely deficient in natural flavor or aroma.

The primary requirement is that the amount selected be effective, i.e., sufficient to alter, modify or enhance the organoleptic characteristics of the parent composition, whether foodstuff per se, chewing gum per se, medicinal product per se, toothpaste per se, or flavoring composition.

The use of insufficient quantities of cyclohexenyl-alpha-alkyl acrolein derivatives of our invention will, of course, substantially vitiate any possibility of obtaining the desired results while excess quantities prove needlessly costly and in extreme cases may disrupt the flavor-aroma balance, thus proving self-defeating. Accordingly, the terminology "effective amount" and "sufficient amount" is to be accorded a significance in the context of the present invention consistent with the obtention of desired flavoring effects.

Thus, and with respect to ultimate food compositions, chewing gum compositions, medicinal product compositions and toothpaste compositions, it is found that quantities of cyclohexenyl-alpha-alkyl acrolein derivatives of our invention ranging from a small but effective amount, e.g., 0.02 parts per million up to about 500 parts per million based on total composition, are suitable. Concentrations in excess of the maximum quantity stated are not normally recommended since they fail to provide commensurate enhancement of organoleptic properties. In those instances wherein the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention are added to the foodstuff as an integral component of a flavoring composition, it is, of course, essential that the total quantity of flavoring composition employed be sufficient to yield an effective cyclohexenyl-alpha-alkyl acrolein derivatives of our invention concentration in the foodstuff product.

Food flavoring compositions prepared in accordance with the present invention preferably contain the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention in concentrations ranging from about 0.0025% up to about 15% by weight based on the total weight of the said flavoring composition.

The composition described herein can be prepared according to conventional techniques well known as typified by cake batters and fruit drinks and can be formulated by merely admixing the involved ingredients within the proportions stated in a suitable blender to obtain the desired consistency, homogeneity of dispersion, etc. Alternatively, flavoring compositions in the form of particulate solids can be conveniently prepared by mixing the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention with, for example, gum arabic, gum tragacanth, carrageenan and the like, and thereafter spray-drying the resultant mixture whereby to obtain the particular solid product. Pre-prepared flavor mixes in powder form, e.g., a fruit-flavored powder mix, are obtained by mixing the dried solid components, e.g., starch, sugar and the like, and the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention in a dry blender until the requisite degree of uniformity is achieved.

It is presently preferred to combine with the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, the following adjuvants: Oil of Cubeb; Phellandrene; β-Phellandrene; Oil of Coriander; Oil of Pimento Leaf, Oil of Patchouli; Natural Lemon Oil; Acetaldehyde; α-Terpineol; Citral; Carvone; Terpinolene; α-Terpinene; Diphenyl; α-Fenchyl Alcohol; Cineole; Limonene; Linalool; Geranyl Acetate; Nootkatone; Neryl Acetate; Heliotropin; Maltol, Vanillin; Ethyl Maltol; Ethyl Vanillin; Anisaldehyde; Alpha Pinene; Beta-Pinene; Beta-Caryophyllene; Dihydrocarveol; Piperonal; Piperine; Chavicine; Piperidine; Oil of Black Pepper; Black Pepper Oleorsin; Capsicum; Oil of Nutmeg; Cardamon Oil; Clove Oil; Separmint Oil; Oil of Peppermint; and C₁₀ -Terpinyl Ethers as described in application for U.S. patent, Ser.

The addition of the mixture of compounds having the structures: ##STR59## to this mixture imparts to the flavor a dominating, full-bodied cinnamon aroma. Without the mixture of compounds defined according to the structures: the flavor formulation is not as intense and requires approximately two times as much material when added to the standard cinnamon flavored powders for use in pastry powders and cake powders. The subject flavor formulation acts as an absolute replacement for cinnamon bark, Ceylon (Cortex cinnamoni ceylanici) when used as a flavor in baking. Thus, 420 grams of the abovementioned flavor formulation are added to the following powder cake flavor oil which is then added at the rate of 0.25% to standard cake mix and appropriately baked:

The mixture is agitated until the gelatin is completely dissolved and the solution is cooled to 120° F. 20 Parts by weight of the liquid flavor composition of Example XV (containing one of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention produced according to Example I or Example II) is then added to the solution which is then homogenized to form an emulsion having a particle size typically in the range of 5-40 microns. The material is kept at 120° F. under which conditions the gelatin will not gel.

Coacervation is induced by adding, slowly and uniformly, 40 parts by weight of 20% aqueous solution of sodium sulfate. During coacervation, the gelatin molecules are deposited uniformly about each oil droplet as a nucleus.

Gelation is effected by pouring the heated coacervate mixture into 1,000 parts by weight of 7% aqueous solution of sodium sulfate at 65° F. The resulting gelled coacervate may be filtered and washed with water at temperatures below the melting point of gelatin to remove the salt.

Hardening of the filtered cake in this example is effected by washing with 200 parts by weight of 30% solution of formaldehyde in water. The cake is then thoroughly washed with water to remove the residual formaldehyde.

EXAMPLE VIII Chewing Gum

100 Parts by weight of chicle are mixed with 4 parts by weight of the flavor prepared in accordance with Example XV. 300 Parts sucrose and 100 parts corn syrup are added. Mixing is effected in a ribbon blender with jacketed side walls of the type manufactured by Baker Perkins Company.

The resultant chewing gum blend is then manufactured into strips 1" in width and 0.1" in thickness. The strips are cut into lengths of 3" each. On chewing, the chewing gum has a pleasant, long-lasting, cinnamon flavor.

EXAMPLE IX Chewing Gum

100 Parts by weight of chicle are mixed with 18 parts by weight of the flavor prepared in accordance with Example XV, Part "B". 300 Parts of sucrose and 100 parts of corn syrup are then added. Mixing is effected in a ribbon blender with jacketed side walls of the type manufactured by the Baker Perkins Company.

The resultant chewing gum blend is then manufactured into strips 1" in width and 0.1" in thickness. The strips are cut into lengths of 3" each. On chewing, the chewing gum has a pleasant, very long-lasting, cinnamon flavor.
